Soon, travelling to space could mean nothing more than just a ride in an elevator, and one ambitious company has already begun collecting funds and drawing up plans for technology as such. Called the Space Elevator project, this one showed up on Kickstarter and basically involves the use of a tethered space elevator, hooked on to a space station with a durable cable, wiping out the need for use of rocket fuels. This in turn could pretty much make space travel affordable and the concept is currently being examined by LiftPort. Also, it might very well take a good 20 years for this to turn into a reality, though LiftPort is currently sculpting out “interim steps” of developing a suitable low-cost way to launch cargo into space.
